How To Install A Soft Start Kit On A Air Conditioner | Run Home AC With A Generator | MicroAir
Вставка
- Опубліковано 7 лип 2024
- In this video I show you how to install a soft start kit on your home air conditioner so you can run your air conditioner using your portable generator. The Micro-air soft start kit lowers the in rush amperage so that you can power it with a generator. Hard start kits are not always the best solution, especially when installing a larger units. Soft start kits are capable of lowering in rush amperage more than hard start kits and will also help preserve your compressor. All of that being said, you will still need a generator capable of whatever amperage the soft start kit brings the air conditioner down to.
Tools and soft start kit in the video:
4 ton+ Micro Air Soft Start Kit: amzn.to/3ZTGM1A
2-3.5 ton Micro Air Soft Start Kit: amzn.to/3kVSjhO

Subscribed. This was exactly what I was looking for and nobody else had it for homes. Thank you!
Im glad it was helpful! Thank you for subscribing!
@@HowToHomeDIY This compressor starter is great to refuce contactor and bearings abuse.
Now go ahead one step further and put a single phase "Schneider soft-starter" on the FAN Motor itself. It will further reduce start surge of Fan and lenghten its life span.
These motors get killed during the start surge when the rotor translates before it can start spining. Capacitors also take a beating by instant surge
Now have credit $523.46cr!
Good information! I subscribed and liked.
My question is can you have a hard start kit on the system and also install the soft start??
@juanresendiz56jr No. Can only be one or the other. Thanks a lot for the feedback!
I installed an Easy Start on my 2.5 ton Trane unit and the results were less than expected, I get frustrated when devices do not work as advertised, I also stated this in a comment on youtube. I was very disappointed, however Micro Air reached out with very highly qualified techs and even a design engineer.
The problem was NOT theirs but with their great customer service they took on the problem of getting my inrush current down to acceptable levels.
My unit has a non-bleed TXV and they have come up with an engineering fix to get my inrush down. GEEZE they even offered to help me change out the TXV if necessary!!!!!
Micro-Air is a great company to do business with, they do stand behind their products!!!
Thanks for reading this,
Roy Agrusa
Wow, that’s awesome! They really do care about their products and customers. Thanks a lot for sharing!
Thanks for the info. What's a non-bleed TXV? Can you explain in mor detail what engineering fix they came up with. That would be helpful.
Just installed one on my 4 ton ac and went from 121 to 34 starting amps, and my 8kw Generac handled it just fine. Totally recommend.😊
They really work well. Same situation here. 4 ton A/C.
It's nice that the soft start allows the indoor blower and outdoor fan to start a few seconds before the compressor. On Generator it gives it time to ramp up a little just as the compressor starts.
Great video. Clear and concise. Thanks for putting this up.
I am wondering about putting regular soft starts on the condenser cooling fan and on the squirrel cage fan. It makes sense that it would improve the life of those motors. This is a video about soft starters in general and it helped me understand how it is without them, and how they reduce the destructive force of direct online operation: ua-cam.com/video/6X71RZWvOvc/v-deo.html
I just installed the system on my American Standard Gold Series 3 ton heat pump. (I gave the full description in the event someone else has the same system) You're directions were very clear and precise. I really appreciate your informative video. Thanks 👌 👍
The best video on YT showing the exact wiring, clear and straight forward. Thanks. Great Job.
Just installed these on two units with this video's help. Hasn't blown up yet. Thanks!
Thanks, we just installed a couple of Tesla Powerwall 2 storage batteries and I wanted a soft start kit to reduce the amp draw when the batteries are running our 3.5 ton Ruud package air conditioner during peak energy hours when the Tesla Gateway switches our home over to off-grid battery-only mode. After finding and watching your video, I bought the same model of soft starter and installed it today. Very easy to do and seems to work as advertised. Thanks for taking the time to make this video.
Oh that sounds cool! I am definitely interested in also having a way to provide electricity in the event of a longer power outage aside from a generator. Have been looking at some solar setups. The Powerwalls are interesting. Glad to hear that this helped!
I installed one of these on my rv. It works great & makes it possible to run the ac on a smaller generator.
Excellent video. Clear, to the point and well-explained and edited!
Much appreciated! Glad you liked it!
Thanks Adam! As a result of watching your video several times, I decided that EasyStart was the right solution for me. I am planning a 9.5kw emergency back-up generator. I also installed an IoTaWatt power monitor so I could see my max loads on each circuit. I measured the inrush at my breaker legs to include the inrush amps to charge the capacitor. I was at 138a on each leg. I measured the running amps including the fan and compressor at 18.7a. I’ll be installing my EasyStart, sized for my 5 T on Saturday. I had to wait until they got some inventory in.
Yeah that is a big unit! I think you will find it very helpful once you install it. I love mine! Generator barely pulls down when my 4 ton kicks on.
@@HowToHomeDIY I finally got my Easy Start unit installed yesterday due to shipping delays. My results on my 5T AC unit were beyond my expectations. My surge amps dropped from 138a per phase to 42+a/phase. But the big surprise was my running amps. They dropped from 19.2a per phase to 13.6a. This was my measurement after 5 starts this morning. That's a 1300 watt savings in my running power and a 69% drop in my surge amps. I decided as a result of running Iotawatt Power Management and these final Easy Start measurements to drop my generator size for this winter to a smaller unit. I am purchasing the WH iGen 4500 which will run all my house circuits except for my large appliances and AC. I may still purchase the WH 9.5kw/12.5kw peak next summer if I want to run AC. But it consumes less than half the fuel during a blackout and most of ours come in the winter! Thanks Adam!! Awesome channel!
@@gottofly2 I don't understand how this unit can reduce the running amps. With all the efficiency mandates these days you'd think every a/c would be required to use one of these!
@@jackmorgan709 after having it for 9 months, I have observed that the running amps stayed marginally the same-19a. The biggest drop was in my inrush amps. 138 to 42a. I ended up purchasing the bigger WH 9500.
@@gottofly2 I went thru the same calculations in my head and just went for the biggest quietest invertor generator I could find that also could be converted to natural gas. You never regret having more wh available, especially when a neighbor is in need.
Think this was the video I needed to see. Have read instructions on web side for micro-air and watched other vids but this is the one that sunk in. Thank you!
Nice! Just what I bought to allow my DIY power wall inverters to operate with a lower inrush. Can't wait to hook it up... Thanks for sharing!
You are very welcome. That sounds interesting!
Excellent video, I just bought a generator and this was exactly what I was looking for. Thank you
Thank you for your great video; I learned a lot from it. I do have an observation, and you may have taken care of it off camera. but you touched the capacitor. You know what you are doing and were careful not to touch the bare connections, but a novice might not know that the capacitor holds a lot of power (even when the power is off) that can even kill.
Excellent explanation! Appreciate you taking the time to thoroughly explain the process. Well Done!
You're very welcome! I am glad it was helpful!
Cap can zap ya pretty good.
A customer told me about these soft starts, told him I would check them out and put one on my own unit. Thank you for the info
You are welcome! My only regret is not installing it sooner! Love this thing.
As I'm sitting in the middle of hurricane Ian I am really enjoying your videos and REALLY want to thank you
Thanks a lot for the feedback! Stay safe! We are waiting for Ian to make his way up to us. Currently just getting the outer rain bands.
@@HowToHomeDIY yeah same here. the thing is parked. Sloooooooow
Excellent. We have a 15K/12K gas generator that runs our AC just fine, but I still want to install a soft start kit. This was very helpful. Thanks.
What size generator do you have?
You have the exact projects that I plan on doing on my house nice video!. Can you just make an updated video of your generac transfer switch working with this soft start? I just want to see what all you can run with the generator and A/C.
Adam, Thanks for your quick response. I couldn't find the HERM label but I found out that it's the one that goes to the compressor. I will attempt the install tomorrow based on your very done video. Wish me luck!
Ok great! Good luck! Let me know how it goes.
For future reference from an hvac tech you could also count the pins for the spade connectors on the capacitor.
4 is common from the contactor
3 is herm for the compressor
2 is fan to the condenser fan motor
MicroAir Easystart is a combo soft start and hard start modification. Should have shown start current after the five training cycles with the actual selected start current showing on sixth startup. Allow 5 mins off time for compressor refrigerant pressures to equalize between training starts. Typically achieve 60% to 70% reduction in startup surge current on compressor. Training should be done on grid, not with generator.
A hardstart kit is just a momentarily large start cap placed across compressor run cap during the half second startup. It is intended for low AC line voltage situations or long wire runs to compressor. It actually increases startup current.
Softstart is a like a 'light dimmer' that ramps up the voltage during the half second startup. With both hard start cap boost and softstart dimmer ramp, the hard start cap is also voltage ramped so it gives the torque boost without the sudden surge current to compressor start winding of a normal hard start kit.
After the start up, the run current is as normally seen before installing MicroAir. The MicroAir does not effect run current. It is bypassed with a relay after the about half second startup cycle to prevent excessive heating of voltage ramp triac.
This is a great device. Can this be used with a heat pump as well?
@@tonylohrman2031 yes
Thanks for the info!. If a hard-start was installed due to issues with an old compressor, would this help prolong it's life?
@@Ryan-dj5ku Lowering the startup surge will reduce stress on compressor. Weak link in EasyStart is the electrolytic start capacitor. Good to buy a spare capacitor to have on hand.
@RCin Fla what do you mean by the capacitor being the weak link? I am asking because I’m going to be doing a new video on micro airs newer model and in prepping for that video I found something very interesting in regards to the capacitor on the ac. So looking for your insight as to what you meant. Thanks.
Best wiring explanation 👍🏼
Thanks for the vid. Bought the same easy soft start kit and hired a licensed HVAC to install it on my 4 ton Rheem for $65. IT WORKS LIKE A CHARM with my Wgen9500 on propane (11200/8500) generator. We’re now ready for the next act of nature here in Texas.
Awesome! That is a good price! You are definitely all setup and prepared. We had some big storms wipe out the power a couple days ago for a few hours. Hooked the generator up to the house and was like we never lost it haha. Thank you for the feedback! Enjoy!
You must live in bfe. No one even knocks at the door here for under $85
Do you know the running amps/kw when you are running the ac on generator power? I am considering the Wgen 9500W thank you.
@@raddadization No kidding. He must already be a next door neighbor/friend/ relative or something.
@@CaptHammer typically when the compressor kicks in, a 4 ton unit runs on about 5,000 watts.
I found this video by chance, and I have to tell you those are some incredible numbers. I am going to place an order for one of these and see if I can get the AC humming on generator power. Hell, if my generator powers nothing else during an outage but the AC I (and the wife) will be happy campers. Thanks for posting this.
Yes everyone stays much happier. Would love to hear what your numbers end up being. Thanks a lot for the feedback Ron!
Your information is awesome! My daughter & I just installed one following your video it worked. Thanks!.
Awesome! Glad it helped! Thanks for the feedback Jack. Enjoy the unit!
One of best videos on micro air easy install. Easy to understand, even better than the one on micr-air UA-cam channel! Excellent zoom in.
Appreciate it!
Thanks for this video. Your connections worked on my Carrier 3.5 ton ac ( 11 years old )
Great video and made my installation a breeze! I included a like in my product review for the vendor where I bought my Micro Air. Many thanks!
Thanks so much for the video and the advice on how a soft start works. I installed a 3 ton soft start and now I can power my AC unit with my 6 KW portable generator with no problems. By the way, the wife is happy, so now the whole house is happy.
Your instructions were spot on! Appreciate the detail of your video.
Thanks man … Had no ideal hooking a generator to your house was this easy!!
Great work my brother ! Thanks for the information on a soft start kit . Be blessed and a blessing & God bless you always and forever my Brother.
Thank you! God bless you too! Thank you for the feedback.
hey Adam thanks for the videos on setting up a generator for your house. I followed your lead and it was far less intimidating plus the soft start was amazing. I'm able to run my 4 ton a/c plus 2 large screen tvs, refrigerator, 2 computers, stereo and lights and 3 battery backups on a 7000watt running inverter generator.
Thats awesome! Now when the power goes out, it will almost be like it didn't. Glad you were able to get it all set up!
So…by adding some capacitance you’re able to ‘run’ just over 10kw ( at 120/240 single phase ) of load on an alternator and prime mover rated for only 7kw at peak output. Slick. I’d love to see it in action.
How long does 1 tank last?
@@jonlee5642 one tank of what?
@a mere bondservant Honestly I just wired up the whole panel and I dont know what the final load was but the only major appliance I ran at once was the a/c but I had my main room running with 4 battery backups, 2 computers, one large tv and a microwave
Just added mine to our 4 ton unit. Runs the AC no problem at 75% load on my Storm Responder 6250. Your video made the install directions crystal clear!!! Thanks man!
Wow that is awesome! These things really are great. Glad you are up and running. Thank you for that feedback! 👍
Are you guys seeing a substantial dip in voltage & hz from the generator when the AC unit starts up? I just damaged both my refrigerators while running whole house on generator. I believe the issue to possibly be a dip in voltage/hz when the AC unit starts up. Just curious to see if you have experienced something similar?
It could have been from what you described but it could also be your generator. If it has a higher THD% it could damage the sensitive boards on whatever you are powering.
@@HowToHomeDIY The THD is less than 5%. It’s a generac Gp17500e
Oh ok. If it’s that low then you should be good there.
Love this! I'm widowed and am trying to figure out how to wire by cabin for a generator and this was the next video. The other one helped also. Thank you for making so simple a "girl" can do it. LOL I'll definitely be watching more if you have any for making wiring simple for this girl.
since the compressor is what uses the most power in a HVAC system then this soft start kit has the potential to substantially reduce the energy cost each month which may even itself self finance the additional cost for the sofstart kit in a few summer months. I am seriously considering to add this to my HVAC even though I am not into making any power panel modifications to use emergency generators or a power wall backup system yet. Great video. just subscribed. Thanks
Adam,
My son and I just finished installing the Micro Air ASY-368-X48 Soft Start gizmo on our 4 ton A/C unit. We followed your instructions to a "T" and the results are as follows:
The IRA before was at 76.9, after the gizmo was installed it dropped down between 30.4 and 33.i Amps.
The running Amps before was between 12.8 and 13.1 and it dropped down to 10.9 Amps after the gizmo.
We attached ours to the side of the A/C unit and put a hoodie over it so that the intense south Florida sun does not bleach out the decal or make the clear plastic cover brittle over the years ( also it protects it from the rain).
We could have not done this without you, thank you so much for posting your informative, detailed video so a layman like myself could accomplish this.
Thank You and GOD BLESS YOU!
Wow, fantastic results! Very similar to mine. I also ended up making a box for mine just to shield it more from the elements and like you said, the sun. I am glad to hear you were able to get it installed and it is working for you! When the next hurricane comes, you are going to love having it! Thank you for the feedback! Always happy to hear when a video helps someone. God bless you too!
Excellent video I have solar and a 3.5 ton trane package unit and my 12kw inverter and only 300 amp hour battery start the ac after installing this exact softstart unit. I tried before installing and it wouldn’t start the eg4 batteries would go in protective mode and shout down. This did the trick. Now I only need more batteries for storage. Thanks again.
Awesome. Glad to hear you are all setup! Thanks a lot for the feedback and enjoy that cool air 😎
Thank you for sharing this information with us.
Wow, very easy install.. Hvac Tech here I'm impressed!
Thanks for the video. I also have been researching this topic so that I can use a soon to be purchased generator for my house A/C. It turns out that these soft start systems are common in Europe. Emerson (which makes all kinds of high end automatic plant level controls) manufacturers a soft start system in Europe which sells for a lot less than what you can find one in the USA; but it is not sold here. If Emerson manufacturers one; I know it is proven technology and feel comfortable buying it. Soft starts are normal for 3-phase motors in a chemical plants so that the equipment lasts longer and you don't pull the large electrical spikes; but I thought they were not an option for single phase electricity like we have in our houses.
I am undecided between the EasyStart 368 and one from Hyper Engineering SS1B16-32SN. It is $249 versus the $350 for the EasyStart 368. Cost entereds into the decision but the main reason I lean to the Hyper Engineering was they provided lots of information on why and how the device works. As a chemical engineer, I like that. Yes, their installation videos are MIA. Previously, I had succesfully used a Hard Start kit for generator operation testing on a 4-ton 2-stage 18SEER compressor but it really hammers the compressor motor. I pulled the hard-start kits out for normal (non-generator) operation; because I did not like the sound my compressors made when they started. These soft start kits work in the opposite manner and should extend the life of the compressor.
Final comment. I no longer will use my old generator because the power it produces has 11-14% THD distortion. Better than many generator but enough to possibly cause problems on some household electronics which includes almost everything in your house. You need
Read instructions, thought man, this is complicated. Watched your video, hooked up no problem & it works great. They need to pay you & put your video on their website. Crystal clear, simple and accurate. Great job my friend. Just tried out today, ran whole house, including 3.5 ton a/c , 2 refrigerators & a freezer on 12k peak portable generator. Saved me thousands of $$$.
Good to hear! Glad it was helpful! Thanks for the feedback Roger. Enjoy the new toy!
Thank You for your video, helped a ton!!!!!
Very detailed. Thank you.
Glad it was helpful!
Excellent, thanks for this. I bought my run start in December and now installing as I'm gonna need it soon. You explanation was excellent! The document on the Micro-air site made me want to lose the will to live. They couldn't even explain what each wire was so I wasn't about to just blindly connect stuff to the kit. With your clear simple explanation I understood what each wire dose and will go ahead with the install. I just don't get why people make something that is so simple sound so frickin complicated! And I'm an electronics engineer! Cheers!
Awesome! Really glad to hear it was helpful. Yeah the instructions are a bit difficult to understand as there are so many different schematics offered. I reached out to them to clarify the instructions before filming this. Hope you enjoy the soft start! Thanks a lot for the feedback!
Sub'd. After watching this a few days ago I decided to have our HVAC guy install this on our 4ton AC. We saw an in rush of nearly 90 and it dropped to 50 after the install.
Awesome results! Do you have the newer bluetooth one or the one like mine? The bluetooth one is interesting to me.
What was the cost of the install and was it tied to a service call or just to install the Soft Start?
Good info! Ty for putting this up!
You are very welcome! Glad you found it helpful. Thank you for the feedback!
Thank you for this video. Keep up the good works my friend.
You are very welcome. Thank you for the kind words!
Great video. It is very informative. I find that the installation of the soft start kit is pretty straightforward. I too have a 4-Ton (Daikins) AC. I have a portable generator, 12K, Duramax, that is connected via a 50 amp transfer switch. I can run everything with the exception of my ac. My ac has a 40 amp double pole breaker. And I'm not sure how to connect it to my transfer switch to power the ac when an outage occurs. I'd like your input. Thank you.
Thankx! Lots of great information!

@@HowToHomeDIY How many tons is your unit? And does this mean that a 30 amp gen cant handle your ac unit?
Thanks Very Much!
Awesome video
You're very welcome! Glad it was helpful!
Great videos, easy to follow step by step
Great video and explanation! I also watched the generator plug video. Any chance you'd mind sharing the specs on the generator you're using?
Very good video thank you
Great content thanks for creating this. Any consideration to the indoor unit powering up and that load? It’s really just the fan in the air handler but is there a way to stage that as well as opposed to it kicking on at the same time?
Turn thermostat to cool/heat off, fan on and then switch to cool once fan is running. Most I’m aware of are staged automatically but this way will assure it is.
Great tutorial. Will use that info. Best to spend a little more $$$ to get it done correctly. I have no problem with that
Absolutely! To me this thing has been worth every penny!
Sweet setup.thanks

Hey Adam, just subscribed. Loved your backup generator videos, and I have used most of your advice. So I am also considering this device, and I am a homeowner, but no amateur. I would also like to trim the peak current with my 3-ton for a generator situation, and this looks like a viable option. Thanks for the detailed connection advice. My question is: Should the harness (I assume supplied) be run in Seal-Tite?
Thanks
Hey welcome aboard! So per the manufacturer through email correspondence they told me it does not need to be in a conduit. And you are correct, it is included and is attached to the unit. Thanks a lot for the feedback. Always good to hear when I have been able to help in some way!
One other important feature of that particular soft start is it will keep the compressor from trying to turn back on after a power glitch. From Memory I think it is like 5 min, that way the refrigerant has time to bleed down and equalize. Great video.
Thanks for that added info!
Not sure if anyone has experience with the Nest thermostat but mine seems to sometimes kick the HVAC off and then immediately back on. I'm wondering how this Micro-air module will interact with whatever logic is causing this. I think it may be related to the Nest "Airwave" feature that is supposed to use the central HVAC fan to circulate residual cool air through the home after turning the compressor off. Curiously I have this feature turned off so I don't know what is happening but I'm worried the Micro air will be a conflict. I will report back with my findings.
@@chillintm I had nothing but problems with my Nest. Most a/c's don't run off JUST temperature, but they are also dehumidifiers. It is part of the design of an a/c system to control both. I say get rid of the Nest like I did and just get a $30 Honeywell thermostat from the Depot.
@@goofsaddggkle7351 interesting info. I have not installed my Micro Air yet, but I do have a nest thermostat-e, and it will cycle off compressor but it’ll be a few minutes before it kicks back on and continues to cool.
Most digital tstats have a 5min delay when power is cut.
Great Video!
Glad you enjoyed it
thanks, very helpful.

Thumbs up 👍 thanks 😎
Thank you. amazing
Adam,
Purchased a Micro-Air "Easy Start 368" for my 5 Ton home A/C. First extended the two 10 gauge and two 14 gauge wires because the ones that came with the unit were short. Probably short for most applications. Micro-Air should really consider shipping the unit longer wires. I followed your instructions and the unit started right up. Now I should be able to use my emergency back up portable generator to run my A/C .
Thank you for sharing.
Awesome! Glad to hear it. We definitely love ours. The folks at micro air told me you can extend the wires if they are too short by splicing some in which is what it sounds like you did. Thanks a lot for the feedback!
5 Ton AC, and installed perfectly, thanks for posting this detailed info was really helpful. L'd & Sub'd
thanks for the vid, it worked great! I did one too, more people need to know about easy start!!! I also added a link to your movie in my description
I agree, so many people don’t know these things exist. I am still super happy with mine! Thanks for the feedback!
Thank You.
You are welcome!
Good video, will take a look at mine
Hi Adam, what a great video I just bought a house this week and I am going to get this switch as soon as I move in. But Is there anything that's made for a refrigerator to do the same thing?
Video was awesome
Thank you very much! Glad it was helpful.
Nice video. This showed a significant drop in current while running. Has this also resulted in any noticeably reduced electric bills?
There's a long video speaking with one of the engineers from MicroAir about these soft start kits and he explained simply that the reduced current is for so brief a time (to get the compressor going) that the amount saved would be negligible (think penny or less) and you wouldn't really notice it. It's more the ability to start the system with less current as well as the side effect of not driving your compressor so hard which will help lengthen the life of the compressor because it's not being subjected to the high inrush current.
Outstanding
Thanks
Thanks for this video. I used it to help me install the Easy-Start on a 3 1/2 ton Carrier. I'm pretty sure yours is a Carrier too, right? Mine went for an in-rush of 107A to 25.5A. Incredible and now I can run my AC on my Generac battery if I lose power.
@@RadioRich100 Those numbers are correct. LRA on an AC is typically at least 100A. And steady state is pretty close to 25A. Why do you think it's not possible? Are you an engineer?
@RadioRich100 that is all incorrect. That is not how the soft starter works. It does not take on 100 amps because that is not what is demanded of it. And a meter that is made to detect in-rush is going to show you what the highest load is. Min/max would not be nearly as accurate.
I do own an in rush meter. The one in this video is not one however but min max can still give an idea as to the before and after inrush. My newer video on this I use a meter with in rush. It isn’t pulsed as you say. That’s not how this works. So no, your information is not correct. If the demand is unchanged then a smaller generator could not operate the ac but with this installed the in rush is greatly lowered and the generator barely hiccups.
@@HowToHomeDIY I also own an inrush meter and I used it. I am also a retired engineer. RadioRich may know about radios but he obviously doesn't know about how ACs work. The way you describe it is what happens. It increases the length of time to turn the compressor on and that's how it reduces inrush. It's not like it takes it up a lot but it doesn't take a lot. It just needs to ramp up over a few seconds rather than demand the LRA all at once.
Great video! Are all models of 3-4 ton AC system have the same wiring set up?
Living in SWFL we went almost 3 weeks with out power. Installing this and the generator plug.
THANKS FOR YOUR VIDEO YOUR INSTRUCTION HELPED ME TO INSTALL MY EASY START-ASY 368.
Great video. Been watching a lot of your stuff. Adam, just curious, but with an inrush amp drop to 31.6 what are your thoughts on pushing the unit with a smaller generator like the CAT rp7500e? 31.6x240 shakes out to be just over 7500 W and well below the starting capacity of a smaller generator. I’m considering both the rp7500e and the rp12000e for my home but am having a hard time getting past the fuel consumption of the rp12000e if a smaller generator could push the AC.... at least on paper that is.
Hey Jacob, yes on paper the Cat 7500e could handle that amperage as its starting wattage is rated at 9,375 (39 amps @240). But I would probably only have the AC on at that time as it wouldn't take a whole lot else being on before you have maxed out its output and making starting the AC up much harder to not possible depending on what is on. As far as the fuel consumption goes, yes the 12,000e does not have the best fuel consumption but you would be able to run your AC and probably quite a lot of your house on top of it so all depends on what you want more. Cats, fuel efficiency I believe is figured assuming 50% load on the generator so keep that in mind as well. But yes I think that the 7500e should be able to handle that amperage with the way you have described it. Thank you for the feedback, I hope this helps!
Bought One looking Forward to Install
Great information! Thank you! What are the specs (amps & watts) on the generator you were using at the time? I know this video is 2 years old and I saw a more recent one where you said you have a larger generator now.
Yeah I still have the same generator. It’s a Cat 12000E. 15,000/12,000 watts. Unfortunately they don’t make it anymore. Thanks for the feedback!
Thanks for video, been considering this for my home AC. The soft start current reduction is great, but had question in running current. It went from 12 amps to 7-8 amps which is great, but not sure what this means. Seems like using less electricity, but is the cooling the same? If it is the same, why don’t manufacturers put soft starts on all their AC units? Thanks again.
Hey Jeff, yes, even though the electrical requirement is less, the cooling remains the same. Basically it is making the startup of you AC unit, more efficient. On the home AC, instead of sending one big blast of electricity all at once, the soft start starts the fan first, then after a few seconds, the compressor kicks on. By doing it this way and gradually ramping up the power, the unit is not drawing as much amperage all at once. In a generator application, running the AC is not the issue, they dont use that much power to run, it is the starting in rush amperage that makes it difficult to impossible without one of these devices. As far as running current, it doesn't affect that much if at all, they are really just for the starting of the AC unit. I have seen different explanations as to why these or hard starts aren't already installed and the answer I saw the most and makes the most sense, is it just adds cost to the manufacturing of the units. Hard start kits were actually fairly common on AC units years ago and some of your more expensive models, from what I have read do have them installed already. So while there is no clear cut answer, those are the answers I have gathered from people in the industry talking about it. I hope this was helpful and answered your questions.
Thank you for detailed reply. I might have to look into doing something like this so I can maybe use my 2000W gas inverter generator. Thank you, again!
@@HowToHomeDIY Some AC units have VFDs installed and have no LRA on the motor, these are super efficient units, but they are expensive of course!
Great video! Did you have to extend the wires when you mounted it so far from the connection points?
Yes, I was told by Micro Air that if you want to mount it further away that you can extend the the wires. Originally that is what I did but I ended up moving it and mounting it right next to the unit on a post. Thanks for the feedback!
Makes sense, Long term saves
Excellent video would have been better if you explained what wires you checked with the amp meter. I asked a AC tech yesterday who was installing my neighbors new AC unit about my lights dimming when my AC system started. He recommended a soft start and said it would cost $800. Not everyone can install these but I'd recommend a soft start. There's this other video by some schmuck plumber that states the soft start killed the compressor. Don't waste your time watching this, he didn't know that the soft start that was installed on the homeowners AC unit was undersized. He didn't bother to check that out. A soft start reduces the inrush current to the motor and if properly sized is good. Thanks again.
I just installed mine and it was just as easy as you made it look. My generator wouldn't start the AC... but NOW.
HVAC pro here.
Hard start kits are for a different task completely they are for aging weaker compressors to give them an extra kick in the butt to start.
Think of it like coffee
Your regular capacitor set it is the regular coffee. Which is great for most people. But some people need that extra jolt with a shot of espresso as well. That’s the hard start.
This is like switching to decaf.
I will definitely get this soft starter. I watched the other video in how to install the generator inlet switch and getting ready to place my order. One last thing and the most important that I need is - The Generator! Now, what size and how much power do I need?😮
Ty
You are welcome! Thanks for the feedback.
Do they make soft start for deep well pumps?
We have an off grid cottage and the pump (120v) initial start up uses 72A.
Very thorough tutorial video on ac compressor, definitely will add to ours in town.
Cheers
Hey Adam, just wanted to say outstanding job. I have been checking this exact unit out for over a year. Finally decided to pull the trigger and purchase. I have read the instructions several times to make sure I can install this. Your video explained it to a tee. Will be installing mine tomorrow. I do have one question, however. The wire that you use to check the in rush amps in the video, is that the starting amp wire? I appreciate all the information you gave, definitely a lot easier to understand than the instructions that came with the unit.
Hey Jack, the wire you are referring to is the compressor common wire. You will find a large gauge wire coming from your contactor and going to the compressor itself. I think you will really like this unit. Definitely makes things more efficient! I am glad the video was helpful. Thank you for the feedback!
Great video... how many kW generator would you recommend for my 4 ton unit?
Great video tks man you save me $1500 is what a A/C company wanted to charge me
What is the LRA rating listed for your compressor on that label? I have a 4 ton ac I'm setting up for home generator use and I'm just curious what yours is compared to mine. Mine is listed at 108 LRA. Not sure how that compares to the actual startup inrush amps but I'm hoping it doesn't require 108 amps to startup! Thanks a bunch!
